Sarafin discussed lessons learned from Artemis I, highlighting the importance of communicating quickly and effectively with team members and using risk informed decision-making tools. After some initial delays that included lightning strikes, the Artemis I mission began with a successful liftoff of NASA’s SLS (Space Launch System) rocket Nov. 16, 2022, from Launch Pad 39B at NASA’s Kennedy Space Center. Over the course of 25.5 days, NASA tested the Orion spacecraft in the harsh environment of deep space before flying astronauts on Artemis II.

Sarafin said it was his first time in the “hot seat,” and stressed the importance for anyone leading a mission management team to prepare for it by talking with those who have been in the same role, naming the individuals who supported him as team chair.

“You have got to find somebody who has walked a mile in those shoes, who understands the dynamics, who understands the cultural aspects of it,” Sarafin said. “They were fantastic team members, fantastic partners to work with, and I am proud to be a part of that team. These guys walked alongside me and kept me out of trouble.”

As Artemis mission manager for the Moon to Mars Program Office at NASA Headquarters, Sarafin provides oversight and responsibility for critical decisions across all flight phases (launch, in-space, and recovery), with support from team members and advisers with technical expertise in various areas. Prior to flight, he acts as a senior technical leader integrating mission requirements, planning, operations, and flight readiness leading to mission execution.

Sarafin said lessons learned from the mission management team for Artemis I included training both a prime and alternate for each position. He also pointed out the importance of training for logistics, and daily effective communications for all team members.

“In summary, have the right team, do your party planning, (and) set clear expectations,” Sarafin said. “Take care of yourself and your team, and use good tools to make decisions.”

Mission Success is in Our Hands is a safety initiative collaboration between NASA’s Marshall Space Flight Center and Jacobs Engineering. The initiative’s goal is to help team members make meaningful connections between their jobs and the safety and success of NASA and Marshall missions.

Charlie Adams Presented with Golden Eagle Award

As part of the forum, Mission Success is in Our Hands presented the 40th Golden Eagle Award to Charlie Adams of the Jacobs Space Exploration Group. Adams was the mission manager for NASA’s Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID).

Bill Hill, director of Safety and Mission Assurance at Marshall, said Adams was recognized for leading the project throughout LOFTID’s life cycle, which culminated with a successful flight in 2022. Hill said LOFTID’s success as a heat shield will benefit NASA’s future missions.

The Golden Eagle Award promotes awareness and appreciation for flight safety, as demonstrated through the connections between employees’ everyday work, the success of NASA and Marshall’s missions, and the safety of NASA astronauts. Management or peers can nominate any team member for the award. Honorees are typically recognized at Shared Experiences forums.

The next Shared Experiences Forum is scheduled for Sept. 5, featuring Dave Dykhoff, former vice president and general manager of the Jacobs Missile Defense Group and the North American Aerospace Defense (NORAD) Operations Group. The forum will be held in Building 4203, Conference Room 1201 for Marshall team members, and available to the public via Teams.

I Am Artemis: Julia Khodabandeh

Unlike most of her friends in the 80s who covered their walls with posters of bands, Julia Khodabandeh plastered hers with posters of rockets and fighter jets.

Khodabandeh’s interest in aerospace and aeronautics developed at a young age. Her parents were avid fans of the Apollo Program and were heavily invested in her education. Khodabandeh’s father always encouraged her to tackle math and science problems without fear. She recalls him telling her that “you can take any problem and break it into smaller pieces.” It’s a philosophy she still uses in solving problems today.

“When I was growing up, my dad would make practice tests the night before my exams,” she said. “It helped me feel more prepared. The confidence I developed for math and science and my passion for aeronautics and aerospace, led me to a NASA career.”

The better part of her 24-year career with NASA has been dedicated to solid rocket boosters at the agency’s Marshall Space Flight Center. Over the past 10 years, she helped develop the twin solid rocket boosters for the agency’s SLS (Space Launch System) rocket, which are the largest and most powerful solid propellant boosters ever flown. They stand at 177 feet tall, and individually generate a maximum thrust of 3.6 million pounds. Together, the twin boosters provide more than 75% of the total thrust to launch SLS for NASA’s Artemis campaign to the Moon.

Khodabandeh graduated from the University of Alabama in Huntsville with a bachelor’s degree in mechanical engineering and a master’s degree in computational fluid dynamics. Early in her career, her work focused on Space Station microgravity material processing furnaces and the Space Shuttle Return-to-Flight Program.  She went on to support the Ares rocket solid rocket booster team as part of the Constellation Program preceding SLS. Her work on the Ares booster helped guide her to her current position on SLS.

Khodabandeh is the motor and pyrotechnic team lead for the SLS Booster Element Office. She supports design, development, certification, production, and operation of the solid rocket motors, booster separation motors, and pyrotechnics for the twin boosters on SLS. Most days, she manages schedules and helps resolve issues with the help of her team.

“The flight hardware and test hardware are all tremendous accomplishments for the team, and behind these accomplishments are hours, weeks, and months of working together to resolve issues and deliver results,” Khodabandeh said. “It’s the people that make us successful, and teamwork is my favorite part of what we do. Someone once said, ‘You have to build a successful team before you can build successful hardware.’ I couldn’t agree more!”

In her spare time, Khodabandeh volunteers at a local rescue mission, where she provides aid to women struggling with substance abuse. She also mentors students in the Huntsville community, where she hopes to pass on the confidence her dad instilled in her, inspiring them to one day be a part of NASA and the Artemis Generation.

As the girl who grew up with posters of rockets on her walls, Khodabandeh says she is incredibly excited to be one of the many who are responsible for sending astronauts around the Moon on Artemis II.

“The incredible success of Artemis I is something that I will never forget,” she said. “We have demonstrated what we’re capable of, and I can’t wait to see what we accomplish going forward on the Artemis Program.”

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

A ‘FURST’ of its Kind: Sounding Rocket Mission to Study Sun as a Star

Editor’s Note: NASA and partners scrubbed the first launch attempt of the FURST Sounding Rocket Mission on Aug. 11 due to issues with the cooling systems. This story will be updated as soon as the next launch attempt is determined.

By Jessica Barnett 

From Earth, one might be tempted to view the Sun as a unique celestial object like no other, as it’s the star our home planet orbits and the one our planet relies on most for heat and light. But if you took a step back and compared the Sun to the other stars NASA has studied over the years, how would it compare? Would it still be so unique?

furst-2.jpg?w=1412
The Full-sun Ultraviolet Rocket SpecTrograph (FURST) undergoes testing at White Sands Missile Range in New Mexico in preparation for launch. The instrument was designed and built at Montana State University. NASA’s Marshall Space Flight Center provided the camera, supplied avionics, and designed and built its calibration system.

The Full-sun Ultraviolet Rocket SpecTrograph (FURST) aims to answer those questions. when it launches aboard a Black Brant IX sounding rocket at White Sands Missile Range in New Mexico.

“When we talk about ‘Sun as a star’, we’re treating it like any other star in the night sky as opposed to the unique object we rely on for human life. It’s so exciting to study the Sun from that vantage point,” said Adam Kobelski, institutional principal investigator for FURST and a research astrophysicist at NASA’s Marshall Space Flight Center.

FURST will obtain the first high-resolution spectra of the “Sun as a star” in vacuum ultraviolet (VUV), a light wavelength that is absorbed in Earth’s atmosphere meaning it can only be observed from space. Astronomers have studied other stars in the vacuum ultraviolet with orbiting telescopes, however these instruments are too sensitive to be pointed to the Sun. The recent advancements in high-resolution VUV spectroscopy now allow for the same observations of our own star, the Sun.

“These are wavelengths that Hubble Space Telescope is really great at observing, so there is a decent amount of Hubble observations of stars in ultraviolet wavelengths, but we don’t have comparable observations of our star in this wavelength range,” said Kobelski. Marshall was the lead field center for the design, development, and construction of the Hubble Space Telescope.

Because Hubble is too sensitive to point at Earth’s Sun, new instruments were needed to get a spectrum of the entire Sun that is of a similar quality to Hubble’s observations of other stars. Marshall built the camera, supplied avionics, and designed and built a new calibration system for the FURST mission. Montana State University (MSU), which leads the FURST mission in partnership with Marshall, built the optical system, which includes seven optics that will feed into the camera that will essentially create seven exposures, covering the entire ultraviolet wavelength range.

Charles Kankelborg, a heliophysics professor at MSU and principal investigator for FURST, described the mission as a very close collaboration with wide-ranging implications.

“Our mission will obtain the first far ultraviolent spectrum of the Sun as a star,” Kankelborg said. “This is a key piece of information that has been missing for decades. With it, we will place the Sun in context with other stars.”

Kobelski echoed the sentiment.

“How well do the observations and what we know about our Sun compare to our observations or what we know of other stars?” Kobelski said. “You’d expect that we know all this information about the Sun – it’s right there – but it turns out, we actually don’t. If we can get these same observations or same wavelengths as we’ve observed from these other sources, we can start to connect the dots and connect our Sun to other stars.”

FURST will be the third launch led by Marshall for NASA’s Sounding Rocket Program within five months, making 2024 an active year for the program. Like the Hi-C Flare mission that launched in April, the sounding rocket will launch and open during flight to allow FURST to observe the Sun for approximately five minutes before closing and falling back to Earth’s surface. Marshall team members will be able to calibrate the instruments during launch and flight, as well as retrieve data during flight and soon after landing.

Kobelski and Kankelborg each said they’re grateful for the opportunity to fill the gaps in our knowledge of Earth’s Sun.

The FURST mission is led by Marshall in partnership with Montana State University in Bozeman, Montana, with additional support from the NASA’s Sounding Rockets Office and the U.S. National Center for Atmospheric Research’s High Altitude Observatory. Launch support is provided at White Sands Missile Range in New Mexico by NASA’s Johnson Space Center. NASA’s Sounding Rocket Program is managed by the agency’s Heliophysics Division.

NASA Challenge Seeks ‘Cooler’ Solutions for Deep Space Exploration

NASA’s Human Lander Challenge, or HuLC, is now open and accepting submissions for its second year. As NASA aims to return astronauts to the Moon through its Artemis campaign in preparation for future missions to Mars, the agency is seeking ideas from college and university students for evolved supercold, or cryogenic, propellant applications for human landing systems.

Human Lander Challenge (HuLC) banner.

As part of the 2025 HuLC competition, teams will aim to develop innovative solutions and technology developments for in-space cryogenic liquid storage and transfer systems as part of future long-duration missions beyond low Earth orbit.

“The HuLC competition represents a unique opportunity for Artemis Generation engineers and scientists to contribute to groundbreaking advancements in space technology,” said Esther Lee, an aerospace engineer leading the navigation sensors technology assessment capability team at NASA’s Langley Research Center. “NASA’s Human Lander Challenge is more than just a competition – it is a collaborative effort to bridge the gap between academic innovation and practical space technology. By involving students in the early stages of technology development, NASA aims to foster a new generation of aerospace professionals and innovators.”

Through Artemis, NASA is working to send the first woman, first person of color, and first international partner astronaut to the Moon to establish long-term lunar exploration and science opportunities. Artemis astronauts will descend to the lunar surface in a commercial Human Landing System. The Human Landing System Program is managed by NASA’s Marshall Space Flight Center.

Cryogenic, or super-chilled, propellants like liquid hydrogen and liquid oxygen are integral to NASA’s future exploration and science efforts. The temperatures must stay extremely cold to maintain a liquid state. Current state-of-the-art systems can only keep these substances stable for a matter of hours, which makes long-term storage particularly problematic. For NASA’s HLS mission architecture, extending storage duration from hours to several months will help ensure mission success.

“NASA’s cryogenics work for HLS focuses on several key development areas, many of which we are asking proposing teams to address,” said Juan Valenzuela, a HuLC technical advisor and aerospace engineer specializing in cryogenic fuel management at Marshall. “By focusing research in these key areas, we can explore new avenues to mature advanced cryogenic fluid technologies and discover new approaches to understand and mitigate potential problems.”

Interested teams from U.S.-based colleges and universities should submit a non-binding Notice of Intent (NOI) by Oct. 6, and submit a proposal package by March 3, 2025. Based on proposal package evaluations, up to 12 finalist teams will be selected to receive a $9,250 stipend to further develop and present their concepts to a panel of NASA and industry judges at the 2025 HuLC Forum in Huntsville, near Marshall, in June 2025. The top three placing teams will share a prize purse of $18,000.

Teams’ potential solutions should focus on one of the following categories: On-Orbit Cryogenic Propellant Transfer, Microgravity Mass Tracking of Cryogenics, Large Surface Area Radiative Insulation, Advanced Structural Supports for Heat Reduction, Automated Cryo-Couplers for Propellant Transfer, or Low Leakage Cryogenic Components.

NASA’s Human Lander Challenge is sponsored by the Human Landing System Program within the Exploration Systems Development Mission Directorate and managed by the National Institute of Aerospace.

Webb Sees Gassy Baby Stars

NASA’s James Webb Space Telescope has captured a phenomenon for the very first time. The bright red streaks at top left of this June 20 image are aligned protostar outflows – jets of gas from newborn stars that all slant in the same direction.

A rectangular image with black vertical rectangles at the bottle left and top right to indicate missing data. A young star-forming region is filled with wispy orange, red, and blue layers of gas and dust. The upper left corner of the image is filled with mostly orange dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. The center of the image is filled with mostly blue gas. At the center, there is one particularly bright star, that has an hourglass shadow above and below it. To the right of that is what looks a vertical eye-shaped crevice with a bright star at the center. The gas to the right of the crevice is a darker orange. Small points of light are sprinkled across the field, brightest sources in the field have extensive eight-pointed diffraction spikes that are characteristic of the Webb Telescope.
In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula.
NASA, ESA, CSA, STScI, Klaus Pontoppidan (NASA-JPL), Joel Green (STScI)

This image supports astronomers’ assumption that as clouds collapse to form stars, the stars will tend to spin in the same direction. Previously, the objects appeared as blobs or were invisible in optical wavelengths. Webb’s sensitive infrared vision was able to pierce through the thick dust, resolving the stars and their outflows.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency). Several NASA centers contributed to the project, including NASA’s Marshall Space Flight Center.

      For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. The full artist’s concept illustration and full caption is shown below. Credits:
      NASA, ESA, CSA, Ralf Crawford (STScI) Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system.
      Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star 155 light-years away using detailed data known as spectra from NASA’s James Webb Space Telescope. (The term water ice specifies its makeup, since many other frozen molecules are also observed in space, such as carbon dioxide ice, or “dry ice.”) In 2008, data from NASA’s retired Spitzer Space Telescope hinted at the possibility of frozen water in this system.
      “Webb unambiguously detected not just water ice, but crystalline water ice, which is also found in locations like Saturn’s rings and icy bodies in our solar system’s Kuiper Belt,” said Chen Xie, the lead author of the new paper and an assistant research scientist at Johns Hopkins University in Baltimore, Maryland.
      All the frozen water Webb detected is paired with fine dust particles throughout the disk — like itsy-bitsy “dirty snowballs.” The results published Wednesday in the journal Nature.
      Astronomers have been waiting for this definitive data for decades. “When I was a graduate student 25 years ago, my advisor told me there should be ice in debris disks, but prior to Webb, we didn’t have instruments sensitive enough to make these observations,” said Christine Chen, a co-author and associate astronomer at the Space Telescope Science Institute in Baltimore. “What’s most striking is that this data looks similar to the telescope’s other recent observations of Kuiper Belt objects in our own solar system.”
      Water ice is a vital ingredient in disks around young stars — it heavily influences the formation of giant planets and may also be delivered by small bodies like comets and asteroids to fully formed rocky planets. Now that researchers have detected water ice with Webb, they have opened the door for all researchers to study how these processes play out in new ways in many other planetary systems.
      Image: Debris Disk Around Star HD 181327 (Artist’s Concept)
      For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. All the frozen water detected by Webb is paired with fine dust particles throughout the disk. The majority of the water ice observed is found where it’s coldest and farthest from the star. The closer to the star the researchers looked, the less water ice they found. NASA, ESA, CSA, Ralf Crawford (STScI) Rocks, Dust, Ice Rushing Around
      The star, cataloged HD 181327, is significantly younger than our Sun. It’s estimated to be 23 million years old, compared to the Sun’s more mature 4.6 billion years. The star is slightly more massive than the Sun, and it’s hotter, which led to the formation of a slightly larger system around it.
      Webb’s observations confirm a significant gap between the star and its debris disk — a wide area that is free of dust. Farther out, its debris disk is similar to our solar system’s Kuiper Belt, where dwarf planets, comets, and other bits of ice and rock are found (and sometimes collide with one another). Billions of years ago, our Kuiper Belt was likely similar to this star’s debris disk.
      “HD 181327 is a very active system,” Chen said. “There are regular, ongoing collisions in its debris disk. When those icy bodies collide, they release tiny particles of dusty water ice that are perfectly sized for Webb to detect.”
      Frozen Water — Almost Everywhere
      Water ice isn’t spread evenly throughout this system. The majority is found where it’s coldest and farthest from the star. “The outer area of the debris disk consists of over 20% water ice,” Xie said.
      The closer in the researchers looked, the less water ice they found. Toward the middle of the debris disk, Webb detected about 8% water ice. Here, it’s likely that frozen water particles are produced slightly faster than they are destroyed. In the area of the debris disk closest to the star, Webb detected almost none. It’s likely that the star’s ultraviolet light vaporizes the closest specks of water ice. It’s also possible that rocks known as planetesimals have “locked up” frozen water in their interiors, which Webb can’t detect.
      This team and many more researchers will continue to search for — and study — water ice in debris disks and actively forming planetary systems throughout our Milky Way galaxy. “The presence of water ice helps facilitate planet formation,” Xie said. “Icy materials may also ultimately be ‘delivered’ to terrestrial planets that may form over a couple hundred million years in systems like this.”
      The researchers observed HD 181327 with Webb’s NIRSpec (Near-Infrared Spectrograph), which is super-sensitive to extremely faint dust particles that can only be detected from space.

      Ten-year-old, Terry Xu of Arcadia, California; 14-year-old, Maggie Hou of Snohomish, Washington; and 17-year-old, Kairat Otorov of Trumbull, Connecticut, winners of the 2024-2025 Power to Explore Student Writing Challenge. NASA/David Lam, Binbin Zheng, The Herald/Olivia Vanni, Meerim Otorova NASA has chosen three winners out of nine finalists in the fourth annual Power to Explore Challenge, a national writing competition designed to teach K-12 students about the enabling power of radioisotopes for space exploration.
      “Congratulations to the amazing champions and all of the participants!
      Carl Sandifer II
      Program Manager, NASA’s Radioisotope Power Systems Program
      The essay competition asked students to learn about NASA’s radioisotope power systems (RPS), likened to “nuclear batteries,” which the agency has used discover “moonquakes” on Earth’s Moon and study some of the most extreme of the more than 891 moons in the solar system. In 275 words or less, students dreamed up a unique exploration mission of one of these moons and described their own power to achieve their mission goals.
      “I’m so impressed by the creativity and knowledge of our Power to Explore winners,” said Carl Sandifer II, program manager of the Radioisotope Power Systems Program at NASA’s Glenn Research Center in Cleveland.
      Entries were split into three groups based on grade level, and a winner was chosen from each. The three winners, each accompanied by a guardian, are invited to NASA’s Glenn Research Center in Cleveland for a VIP tour of its world-class research facilities this summer.
      The winners are:
      Terry Xu, Arcadia, California, kindergarten through fourth grade Maggie Hou, Snohomish, Washington, fifth through eighth grade Kairat Otorov, Trumbull, Connecticut, ninth through 12th grade “Congratulations to the amazing champions and all of the participants! Your “super powers” inspire me and make me even more optimistic about the future of America’s leadership in space,” Sandifer said.
      The Power to Explore Challenge offered students the opportunity to learn about space power, celebrate their own strengths, and interact with NASA’s diverse workforce. This year’s contest received nearly 2,051 submitted entries from all 50 states, U.S. territories, and the Department of Defense Education Activity overseas.
      Every student who submitted an entry received a digital certificate and an invitation to the Power Up virtual event held on March 21. There, NASA announced the 45 national semifinalists, and students learned about what powers the NASA workforce.
      Additionally, the national semifinalists received a NASA RPS prize pack.
      NASA announced three finalists in each age group (nine total) on April 23. Finalists were invited to discuss their mission concepts with a NASA scientist or engineer during an exclusive virtual event.
      The challenge is funded by the Radioisotope Power Systems Program Office in NASA’s Science Mission Directorate and administered by Future Engineers under a Small Business Innovation Research phase III contract. This task is managed by the NASA Tournament Lab, a part of the Prizes, Challenges, and Crowdsourcing Program in NASA’s Space Technology Mission Directorate.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      https://youtu.be/63uNNcCpxHI How are we made of star stuff?

      Well, the important thing to understand about this question is that it’s not an analogy, it’s literally true.

      The elements in our bodies, the elements that make up our bones, the trees we see outside, the other planets in the solar system, other stars in the galaxy. These were all part of stars that existed well before our Sun and Earth and solar system were even formed.

      The universe existed for billions of years before we did. And all of these elements that you see on the periodic table, you see carbon and oxygen and silicon and iron, the common elements throughout the universe, were all put there by previous generations of stars that either blew off winds like the Sun blows off a solar wind, or exploded in supernova explosions and thrust their elements throughout the universe.

      These are the same things that we can trace with modern telescopes, like the Hubble Telescope and the James Webb Space Telescope, the Chandra X-ray Observatory. These are all elements that we can map out in the universe with these observatories and trace back to the same things that form us and the elemental abundances that we see in stars now are the same things that we see in the Earth’s crust, we see in asteroids. And so we know that these are the same elements that were once part of these stars.

      So the question of, “How are we made of star stuff?”, in the words of Carl Sagan, “The cosmos is within us. We are made of star stuff. We are a way for the universe to know itself.”

      4 Min Read NASA Marshall Fires Up Hybrid Rocket Motor to Prep for Moon Landings
      NASA’s Artemis campaign will use human landing systems, provided by SpaceX and Blue Origin, to safely transport crew to and from the surface of the Moon, in preparation for future crewed missions to Mars. As the landers touch down and lift off from the Moon, rocket exhaust plumes will affect the top layer of lunar “soil,” called regolith, on the Moon. When the lander’s engines ignite to decelerate prior to touchdown, they could create craters and instability in the area under the lander and send regolith particles flying at high speeds in various directions.
      To better understand the physics behind the interaction of exhaust from the commercial human landing systems and the Moon’s surface, engineers and scientists at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently test-fired a 14-inch hybrid rocket motor more than 30 times. The 3D-printed hybrid rocket motor, developed at Utah State University in Logan, Utah, ignites both solid fuel and a stream of gaseous oxygen to create a powerful stream of rocket exhaust.
      “Artemis builds on what we learned from the Apollo missions to the Moon. NASA still has more to learn more about how the regolith and surface will be affected when a spacecraft much larger than the Apollo lunar excursion module lands, whether it’s on the Moon for Artemis or Mars for future missions,” said Manish Mehta, Human Landing System Plume & Aero Environments discipline lead engineer. “Firing a hybrid rocket motor into a simulated lunar regolith field in a vacuum chamber hasn’t been achieved in decades. NASA will be able to take the data from the test and scale it up to correspond to flight conditions to help us better understand the physics, and anchor our data models, and ultimately make landing on the Moon safer for Artemis astronauts.”
      Fast Facts
      Over billions of years, asteroid and micrometeoroid impacts have ground up the surface of the Moon into fragments ranging from huge boulders to powder, called regolith. Regolith can be made of different minerals based on its location on the Moon. The varying mineral compositions mean regolith in certain locations could be denser and better able to support structures like landers. Of the 30 test fires performed in NASA Marshall’s Component Development Area, 28 were conducted under vacuum conditions and two were conducted under ambient pressure. The testing at Marshall ensures the motor will reliably ignite during plume-surface interaction testing in the 60-ft. vacuum sphere at NASA’s Langley Research Center in Hampton, Virginia, later this year.
      Once the testing at NASA Marshall is complete, the motor will be shipped to NASA Langley. Test teams at NASA Langley will fire the hybrid motor again but this time into simulated lunar regolith, called Black Point-1, in the 60-foot vacuum sphere. Firing the motor from various heights, engineers will measure the size and shape of craters the rocket exhaust creates as well as the speed and direction the simulated lunar regolith particles travel when the rocket motor exhaust hits them.
      “We’re bringing back the capability to characterize the effects of rocket engines interacting with the lunar surface through ground testing in a large vacuum chamber — last done in this facility for the Apollo and Viking programs. The landers going to the Moon through Artemis are much larger and more powerful, so we need new data to understand the complex physics of landing and ascent,” said Ashley Korzun, principal investigator for the plume-surface interaction tests at NASA Langley. “We’ll use the hybrid motor in the second phase of testing to capture data with conditions closely simulating those from a real rocket engine. Our research will reduce risk to the crew, lander, payloads, and surface assets.”
